causes

conflict

1, IP address is the equivalent of each computer's unique ID number, like your ID card, like, everyone's not the same number of It is impossible for someone else's ID number to be the same as yours. In a LAN environment, for example, if your computer's IP setting is 192.168.2.10 and the other computer's IP is also set to 192.168.2.10, then Causes IP to conflict with other systems.

2, virus problem: caused by LAN ARP virus attack. ARP, the address resolution protocol, implements its physical address through an IP address. The ARP protocol is a protocol of the TCP/IP protocol suite for translating network addresses into physical addresses (also known as MAC addresses). The ARP virus is not the name of a certain virus, but a general term for a type of virus that spreads the vulnerability of the ARP protocol. Currently, there are two types of ARP attacks on the Internet: gateway spoofing and route spoofing. It is a virus Trojan that invades a LAN computer. The threat to computer users' private information is great.

3. If your computer is in a LAN environment, it may be that the IP settings of other people's computers are the same as your computer's IP settings.

Solution

1. Set to be automatically obtained by DHCP

The error message described is the IP address set by the network card and another one on the network. The IP address of the computer or other network device conflicts. The so-called conflict uses the same address. For example, 00:20:ED:9E:55:B6 in the error message is the MAC address of another computer or network device.

If your IP address is set to a fixed IP address, if you set it yourself, you can set another one. If it is assigned by the administrator, you need to contact the administrator to report the IP address conflict and request to change the IP address. Address or find the computer that caused the conflict to fix.
